I successfully copied a dvd to my hard drive using DVD Shrink and created a new dvd using Imgburn. (Thanks for your help on how to do that.) However, I would like to shorten the copy that is now on my hard drive. So, can I edit those Audio TS/Video TS files on the hard drive somehow or do I have to go back and re-author a new copy to the hard drive?

I want to copy only portions of a dvd I recorded from tv. Can ImgBurn allow me to copy only those portions I want and if so where can I find support to do so?
